First theoretical framework of Al 9 N 9 and B 9 N 9 nanorings for unveiling their unique detection and sensing potential for SF 6 decomposition gases (H 2 S, SO 2 , SOF 2 , and SO 2 F 2 ): toward real-time gas sensing in high-voltage power systems

Al 9 N 9 and B 9 N 9 nanorings are explored via DFT for sensing toxic SF 6 decomposition gases. High adsorption, sensitivity, and fast recovery highlight their real-time potential for fault diagnosis in high-voltage power systems.
